Обсуждение: dbf to pgsql

Hi,
Im lookig for tool to regulary transfer data from dbf files into pgsql.
Would be excellent if the tool would have data tranformation
possibility.

regards
Peter

Peter,

There is a dbf2pg in the contrib library, I have tried to use it, but I had
some probems with it: I had a numeric field whose decimal length was 0.
Dbf2pg couldn't handle this situation, it said that it has an illegel number
format. So I had to generate manually a big convertion script, and I fed to
psql.
EMS has a Data Import tool, it can handle DBF too.

Best Regards,
Otto

Hi,

Is there any easy way to explain analyze a query, which is inside an sql
stored procedure? I could of course copy the query out of the procedure, and
explain analyze it but this is a slower process. I would do this with a lot
of procedures, that's why it should be fast.

create function myquery() returns setof record as $$
    select * from mytable; --this is a set returning query
$$ language sql;

explain analyze select * from myquery();

For me this shows function scan, and not the plan of the query itself.

Best Regards,
Otto

A simplistic approach but workable would be to use the dbfinfo/dbfdump
programs which are part of the shapelib tools at www.maptools.org.

These allow you to dump the data description & data itself as text which
could then be COPY'd into a table built in Postgres.

An ODBC link may also work, but it's not something I've tried, (I have a
feeling there is an ODBC driver for dbf files, if not then the above dumps
can be opened with teh ODBC text driver & transferred to Postgres.
